虹吸

虹 = 工 + 虫 : Helga Horse (hu) wants to decorate engine's entrance ((e)ng2) by putting a rainbow (虹) over it. Before she can install the rainbow she first has to set up a steel beam (工) as support though. Fortunately there is a very strong mosquito (虫) who helps her to set up the beam above the entrance.

吸 = 及 + 口 : Just when Marie Curie (xi) and Yuwen Huaji (及) were on a space trip in front of the space station (Ø1) they encountered an emergency: the failure of their oxygen supply. Their last hope is a hollow mandarin (口) they brought, out of which they suck (吸) their oxygen.
